DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention is further described in combination with the drawings and embodiments:
[0030] See attached Figure 1 As shown, a device for automatically releasing ship lifesaving equipment includes a fixing frame 1, a rotating assembly 2, a line-retracting assembly 3, a lifting assembly 4, a landing assembly 5 and a lifebuoy 6;
[0031] Among them, the fixing frame 1 is arranged at the bulwark position of the ship to play a fixing role of the whole device, and the top of the fixing frame 1 is connected with the retractable line assembly 3 through the rotating assembly 2, so that the horizontal angle position of the retractable line assembly 3 can be adjusted, and the line end of the retractable line assembly 3 is connected with the lifebuoy 6, so that after the retractable line assembly 3 performs the line release action, the position of the lifebuoy 6 dropped on the water surface can be adjusted, which helps to improve the accuracy of the release of the lifebuoy 6, so that the lifebuoy 6 can fall near the target more accurately, and increase the chance of the rescued person being rescued. When the rescued person is rescued by the lifebuoy 6, after the retractable line assembly 3 performs the line retracting action, the position of the lifebuoy 6 is transferred to the waterline position of the ship, that is, the rescued person is transferred to the waterline position of the ship together with the movement of the lifebuoy 6.
[0032] In addition, the bottom of the fixing frame 1 is connected to the landing assembly 5 through the lifting assembly 4, so that the landing assembly 5 is moved down to the waterline position of the ship and connected to the lifebuoy 6, so that after the rescued person moves up to the landing assembly 5, the lifting assembly 4 and the retractable line assembly 3 operate to lift the rescued person to the ship's bulwark position.
[0033] In the above embodiment, the device is fixedly set at the bulwark position of the ship. When a person falls into the water, the lifebuoy 6 is dropped at a fixed point near the rescued person by operating the rotating component 2 and the retracting and releasing line component 3, so that the rescued person holds the lifebuoy 6 tightly. At the same time, the lifting component 4 operates to drop the landing component 5 to the waterline position of the ship. Subsequently, under the action of the retracting and releasing line component 3, the rescued person holding the lifebuoy 6 is made to approach the waterline position of the ship and contact the landing component 5. Then, the rescued person moves up to the landing component 5. Under the action of the lifting component 4 and the retracting and releasing line component 3, the landing component 5 moves up to the initial position, so that the rescued person is lifted to the bulwark position of the ship, and the lifebuoy 6 is also moved up to the initial position and placed. Finally, the rescued person climbs over the bulwark position of the ship and can return to the ship's deck.
[0034] In the above solution, the structure of the rotating component 2 is specifically:
[0035] See attached Figure 1 and attached Figure 2 As shown, the rotating assembly 2 includes a rotating roller 21, a turntable 22, an operating rod 23, an electromagnetic ring 24 and a metal ring 25; the rotating roller 21 is vertically rotatably arranged on the top of the fixed frame 1, and a turntable 22 is arranged thereon, and an operating rod 23 is arranged on the turntable 22 so that the rescuer can adjust the position of the turntable 22 in the horizontal direction by adjusting the operating rod 23, and an electromagnetic ring 24 is also arranged on the upper plate of the turntable 22, and the electromagnetic ring 24 is sleeved on the outside of the rotating roller 21 and in the initial state, it is magnetically matched with the metal ring 25 arranged at the bottom of the turntable 22, so that the electromagnetic ring 24 is energized to electromagnetically adsorb the metal ring 25, so that the position of the turntable 22 is fixed and in a non-rotatable and adjustable state, and when the electromagnetic ring 24 is powered off, the position of the turntable 22 can be adjusted.
[0036] During the implementation of this solution, the electromagnetic ring 24 is magnetically attracted to the metal ring 25 in the initial state. At this time, the position of the turntable 22 is fixed and locked. When rescue is needed, the electromagnetic ring 24 is powered off to make the position of the turntable 22 adjustable. At this time, the operating lever 23 is adjusted to make the turntable 22 rotate quickly to the appropriate position, so that the lifebuoy 6 is aligned with the position of the person to be rescued.
[0037] In the above solution, the structure of the retractable wire assembly 3 is as follows:
[0038] See attached Figure 1 and attached Figure 3As shown, the retractable wire assembly 3 includes a bracket 31, a telescopic cylinder 32, a mounting seat 33, an inner hole seat, a mounting box 35, a winch 36 and an electromagnetic block 37; the bracket 31 is arranged on the turntable 22, and a telescopic cylinder 32 is horizontally arranged thereon, the telescopic end of the telescopic cylinder 32 is connected to the inner hole seat through the mounting seat 33, the mounting box 35 is arranged on the turntable 22 and a winch 36 is installed therein, the winch 36 line body extends to the outside of the mounting box 35 and passes through the inner hole seat to be connected to the electromagnetic block 37, the electromagnetic block 37 is energized in the initial state and adsorbs the inner hole seat to limit the initial position of the lifebuoy 6, and the lifebuoy 6 is connected to the end of the winch 36 line body.
[0039] During the implementation of this scheme, in the initial state, the telescopic cylinder 32 is in a retracted state, the winch 36 is in a retracted state, and the electromagnetic block 37 is energized to be magnetically attracted to the inner hole seat. At this time, the initial position of the lifebuoy 6 is fixed and is at the side wall of the ship. When rescue is needed, the telescopic cylinder 32 is extended, the winch 36 pays off the line, and the electromagnetic block 37 is powered off. At this time, the position of the lifebuoy 6 can be adaptively changed. According to the specific position of the rescued person, the lifebuoy 6 can be moved forward to above the rescued person by extending the telescopic cylinder 32, and as the winch 36 pays off the line, the inner hole seat can impose certain restrictions on the swing position of the winch 36 line body, so that the lifebuoy 6 can fall more accurately near the rescued person.
[0040] In the above solution, the structure of the lifting component 4 is as follows:
[0041] See attached Figure 1 and attached Figure 4 As shown, the lifting assembly 4 includes a fixed box 41, a second winch 42, a guide tube 43, a connecting seat 44, a traction line 45 and an ear plate 46; the fixed box 41 is arranged at the bottom of the fixed frame 1, and the second winch 42 is installed therein, the line body of the second winch 42 extends to the outside of the fixed box 41 and passes through the guide tube 43 arranged at the bottom of the fixed box 41 to be connected to the connecting seat 44, the connecting seat 44 is connected to an ear plate 46 through at least four traction lines 45, and the landing assembly 5 is connected to the ear plate 46.
[0042] During the implementation of this scheme, in the initial state, winch 2 42 is in a reeled state. When rescue is needed, winch 2 42 can release the line, and the setting of the guide tube 43 can limit the line body of winch 2 42 during the releasing process. At the same time, by setting at least four traction lines 45, the lifted weight can be dispersed to multiple fulcrums, reducing the pressure on a single traction rope, which not only increases the carrying capacity, but also reduces the risk of accidents caused by failure of a single component. Moreover, multiple traction ropes can be tightened from different angles to form a more stable lifting structure, which can improve the balance performance and better stability during the transfer of the rescued person.
[0043] In the above solution, the structure of the footrest assembly 5 is as follows:
[0044] See attached Figure 1 and attached Figure 5 As shown, the landing assembly 5 includes an outer shell 51, a second telescopic cylinder 52, a guide block 53, a support rod 54 and a flat plate 55; one side of the outer shell 51 is open and the top is connected to the ear plate 46, the second telescopic cylinder 52 is horizontally arranged in the outer shell 51, and the guide block 53 is also connected to the support rod 54 through a sliding arrangement in the outer shell 51, and the support rod 54 and the telescopic end of the second telescopic cylinder 52 are commonly connected to the flat plate 55, and the flat plate 55 is slidably arranged in the outer shell 51, so that the second telescopic cylinder 52 operates to extend the flat plate 55 to the outside of the outer shell 51 to form a space for the rescued person to step on;
[0045] During the implementation of this solution, in the initial state, the flat plate 55 is stored in the outer shell 51. When rescue is needed, the telescopic cylinder 52 operates to extend the flat plate 55 to the outside of the outer shell 51. During the process, the setting of the guide block 53 and the support rod 54 can improve the connection effect of the flat plate 55, so that the flat plate 55 is more stable after being extended to the outside of the outer shell 51. At this time, the flat plate 55 forms a space outside the outer shell 51 for the rescued person to step on;
[0046] Among them, considering the use effect of the footrest assembly 5, for this reason, refer to the attached Figure 5 As shown, the landing assembly 5 also includes a float 56 and a ball 57; the float 56 is arranged at the bottom of the outer shell 51 to contact the water surface during the rescue process. After the float 56 contacts the water surface, the stability of use can be improved. There are a plurality of ball 57 and they are arranged inside the outer shell 51 to form a rolling cavity in contact with the flat plate 55, so that the wear of the flat plate 55 is reduced during the movement of the flat plate 55, thereby improving the service life.
[0047] In the specific implementation process of the present invention, when rescuing, the electromagnetic ring 24 is powered off, and the turntable 22 is quickly rotated to a suitable position, so that the lifebuoy 6 is aligned with the position of the rescued person; then, with the cooperation of the telescopic cylinder 1 32 and the winch 1 36, the lifebuoy 6 is lowered to the position of the rescued person. At the same time, the winch 2 42 operates to lower the outer shell 51 to the waterline position of the ship, and the telescopic cylinder 2 52 operates to push the flat plate 55 out of the outer shell 51 to form a space for the rescued person to step on; as the reeling action of the telescopic cylinder 1 32 and the winch 1 36 unfolds, the rescued person holding the lifebuoy 6 is moved closer to the rescued person. There is a space for the rescued person to step on. When the rescued person is transferred to the space for the rescued person to step on, at this time, the telescopic cylinder 1 32 and the winch 1 36 return to the initial state. At the same time, the winch 2 42 is reeled in so that the rescued person is lifted to the position of the ship's bulwark. Finally, the rescued person can climb over the ship's bulwark and return to the ship's deck. At the same time, the telescopic cylinder 2 52 contracts to store the flat plate 55 into the outer shell 51. In addition, considering that the rescued person can easily climb over the ship's bulwark, a ladder structure is formed between the fixed frame 1, the fixed box 41 and the space for the rescued person to step on, so that the rescued person can climb.
[0048] Among them, in the above scheme, in order to improve the stability of the footrest assembly 5 in the initial state, so that when the rescued person is at the bulwark position of the ship, the entire space for the rescued person to step on can be more stable, for this purpose, refer to the attached Figure 1 , Attachment Figure 6 And attached Figure 7 As shown, a guide assembly 7 is installed at the bottom of the lifting assembly 4, and the guide assembly 7 is connected to the landing assembly 5, so that the landing assembly 5 can remain stable after being docked and guided to the initial state by the guide assembly 7 during the upward movement; specifically, the guide assembly 7 includes a guide shell 71, a docking tube 72, a spring 73, a docking block 74, an insertion rod 75 and a guide wheel 76; the guide shell 71 is a truncated cone structure that is narrow at the top and wide at the bottom, and four docking tubes 72 are arranged on its inner circumference, and the four docking tubes 72 are connected to the docking blocks 74 slidably arranged in the docking tubes 72 through springs 73, the insertion rod 75 is the same in number as the docking tubes 72 and is vertically arranged at the top of the outer shell 51 and corresponds to the docking tubes 72, and the docking tubes 72 are provided with guide wheels 76.
[0049] During the implementation of this scheme, as the landing assembly 5 moves upward, the guide wheel 76 is in the guide shell 71 and continuously contacts the inner wall of the guide shell 71 until the four guide wheels 76 are in contact with the guide shell 71. At this time, the insertion rod 75 is inserted into the docking tube 72. At this time, the landing assembly 5 is limited in the circumferential direction.
[0050] In addition, considering that the rescued can easily climb over the ship's bulwark, Figure 8 As shown, a ladder 8 is provided on the fixing frame 1 , and the ladder 8 is located on the side of the lifting assembly 4 and the landing assembly 5 .
[0051] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
